Modular three-phase PV inverters for commercial sites.
NexusPlus is NovaFir’s commercial and institutional power-conversion family: three-phase, grid-tied, modular, and designed for large rooftops, campuses and distributed commercial PV.
Planned classes and current product direction, not certified shipping SKUs. Electrical configuration, protection architecture and certification remain engineering-validation items.
NexusPlus is not a larger Nexus.
The name describes a family relationship, not a capacity step. NexusPlus is a different architecture built for a different customer, and it is not an all-in-one hybrid inverter.
Dedicated commercial PV power conversion
- ›Three-phase, grid-tied PV inverter and string-inverter architecture
- ›Modular deployment across large arrays
- ›Designed for commercial rooftops, campuses and distributed commercial PV
- ›Integrates natively with NovaCloud Commercial
- ›Coexists with Atlas, ASCEND, third-party BESS and existing site systems
Not an all-in-one residential-style hybrid
- ›Not an all-in-one hybrid inverter with an integrated battery architecture
- ›Not a scaled-up version of the 48 V Nexus family
- ›Not a single multi-megawatt inverter
- ›Not a requirement for NovaCloud, Atlas or ASCEND customers
- ›Not a reason to replace functioning third-party equipment
Four planned classes, sized to real commercial blocks.
Thirty closes the gap between Nexus and serious three-phase commercial PV without forcing a 50 kW minimum. Above that, the classes follow how commercial arrays are actually built.
Regional electrical variants are planned in a North American 277/480 V three-phase direction and an international 400 to 415 V three-phase direction. Neither should be read as already engineered or certified, and market-specific configurations will vary by region.
Built for the buildings that run all day.
NovaFir’s initial commercial focus includes distributed and commercial sites below approximately 25 MW. That is a focus decision rather than a technical ceiling in the NovaCloud or Atlas architecture.

Power conversion here, intelligence elsewhere.
Each layer keeps its own job. NexusPlus does not need to become a site controller, and the platform does not need NexusPlus to be useful.
NexusPlus
Local PV power conversion and MPPT, with local protection at the inverter.
NovaCloud Commercial
Multi-site monitoring, analytics, fleet visibility and commercial diagnostics across the site or portfolio.
Atlas
May support broader commercial site integration where the site has wider OT requirements.
ASCEND
Advanced operational optimization where site complexity justifies it.
Scaling to multi-megawatt systems is achieved through multiple inverter blocks and normal commercial aggregation and protection architecture, not by building a single multi-megawatt NovaFir inverter.
A power-conversion option, not an obligation.
NexusPlus is a NovaFir power-conversion option for new commercial PV installations or end-of-life inverter replacement where it fits the site. Existing NovaCloud and Atlas customers are not expected to replace working third-party inverters, and there is no commercial logic in recommending it when the economics do not support it.
See the commercial stack →New commercial PV
Specified into a new rooftop, campus or distributed commercial array from the start, with native NovaCloud integration.
End-of-life replacement
Considered when existing inverters reach end of service life and replacement is happening anyway.
Replacing equipment that works
If third-party hardware is performing and supported, the honest answer is to monitor it through NovaCloud and leave it in place.
Clear scope, reviewable supply chain.
The initial NexusPlus story is PV power conversion. Storage integrates as a separate asset or system where it is commercially justified, rather than being forced into the first product as a combined PV and battery conversion platform.

Component traceability for procurement review
Architecture informed by IEC 62443 and NIST SP 800-82
Designed for serviceability, update paths and lifecycle availability
OT architecture informed by IEC 62443 and NIST SP 800-82. Electrical, grid and safety certifications are planned and targeted by market rather than achieved, and launch sequencing remains subject to engineering validation.
Specifying commercial PV hardware?
If you’re an EPC, operator or institutional owner planning commercial PV, we’d welcome a conversation about where NexusPlus fits and where it does not.
